NON-REFILLABLE BOTTLE.

To all whom it may concern:

Be it known that I, WILLIAM R. MCDON- ALD, citizen of the United States, residing at Dallas, in the county of Polk and State of Oregon, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

My invention relates to stoppers to be applied to bottles for the purpose of preventing the refilling of the same, and in its broad features the invention includes a tubular stopper adapted to be inserted into the neck of a bottle having springs for preventing the removal of the stopper from the neck. This stopper is provided at one end with an internally opening valve which is normally held closed, so as to close the bottle and prevent the evaporation of liquid, by means of a screw threaded shaft adapted when turned inward to contact with the valve, but when turned outward to permit the valve to open to a limited extent. This screw threaded shaft is provided exteriorly with a head whereby it may be turned inward, with one or more screw blades or helices which extend the length of the shaft and act as baffles to prevent the insertion of any instrument, whereby the valve may beheld open while at the same time permitting the free outlet of liquid.

For a full understanding of the invention and the merits thereof and also to acpuire a knowledge of the details of construction, ref erence is to be had tothe following description and accompanying drawing, in which:

Figurel is a longitudinal diametrical section of the upper end of a bottle with my improved stopper applied thereto; Fig. 2 is a like view showing the bottle inverted; and, Fig. 3 is a perspective detail enlarged of the valve in the lower end of the stopper.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawing by the same reference characters.

Referring to these fi ures, A, designates a bottle having the neck, B, provided with the inwardly extending annular rib 2 roviding a recess 3 in the neck of the bottle beneath the rib.

The stopper proper consists of a tube 5 of metal, rubber, glass, or other suitable material having thereon the upwardly and outwardly extending springs 6. If the tube is of metal these springs are soldered to the tube and are so arranged that when the Specification of Letters Patent.

Serial No. 505,681.

stopper is inserted in the bottle the springs will be compressed and will then spring outward after they have passed the shoulder or rib 2, so as to hold the stopper in place. The upper end of the tube 5 is provided with a sleeve 6 of cork or other compressible material, and the flange 7 which cont-acts with the upper end of the bottle mouth. The tube, as will be seen, extends up beyond the ring 6 of cork and is provided at one side withan outlet lip or mouth 8.

9 designates a longitudinally extending shaft which is mounted at its upper end in a screw threaded bearing 10 formed in the closed end of the tube 5. The upper end of this shaft isscrewthreaded, as at 11, and the lower end of the shaft is formed with a knob 12.

The lower end of the tube is formed with an ordinary valve seat 13 upon which is pivoted or otherwise secured a hinged and weighted valve 14, the under face of the valve being covered with rubber, cork, or other material, which will act to prevent the passage of liquid passing the valve when the valve is closed. The knob 12 is adapted to contact with the upper face of this valve and hold it closed when the shaft 9 is turned to its full inward position.

In order to prevent the insertion of any instrument into the stopper which will act to lift the valve 14 and hold it lifted, I provide baffles mounted preferably upon the shaft 9, these bafiies each having the form of a helix or double screw which depends from the shaft and fills the tube 5. It will be obvious that while liquid may pass down ward between the blades of the screw when the bottle is inverted, yet the screw will prevent the insertion of any instrument which might damage the valve, or otherwise prevent its operating. It will be seen that by reason of the helical blades mounted on the shaft and forming the baflies, that i an instrument such as a wire inserted into the mouth of the bottle will be guided down to the upper face of the valve so that the wire or other implement will. strike the valve and close the same, it being impossible by reason of the helical blades to insert a wire tion; and comparatively cheap in construction.

Having thus described the invention what is claimed as new is:

1. A non-refillable bottle having a neck, a tube inserted therein, said tube being open at its upper end, an outwardly opening valve at the lower end of the tube, and a screw-threaded rod entering the upper end of the tube and engaging at its lower end with the valve to hold it closed or allow it to open, that portion of the rod projecting into the tube being formed with screw blades surrounding the axis of the rod and entirely filling the cross section of the tube.

2. In a non-refillable bottle, a bottle neck, a. tube inserted therein, said tube having a valve seat at its lower end and a side opening at its upper end provided with a lip, means on the tube engaging with the bottle neck for preventing the withdrawal of the tube, a shaft passing longitudinally through the tube and having a screw threaded engagement therewith, a head on the end of the shaft, a knob on the inner end of the shaft, a valve seat formed on the lower end of the tube, a valve mounted on said seat to close against the same with which the knob on the end of the shaft is adapted to contact, and baffies mounted on the shaft for preventing the insertion of a tool, said baflies having the form of a helix surrounding the shaft, said helix entirely filling the cross section of the tube.

3. In a non-refillable bottle, a bottle neck having recesses formed on its inside face, atube inserted into said bottle neck, the lower end of said tube being formed with a valve seat and the upper end of the tube being provided with a laterally extending open mouth, upwardly and outwardly ex tending springs attached to the lower end of the tube and adapted to spring into the recesses of the bottle neck, a stopper surrounding the tube adapted for insertion in the mouth of the bottle, a valve hinged to the inside face of the valve seat and closing against the same, a shaft extending lon 'itudinally through the tube having at its lower end a knob adapted to contact with the valve and hold it closed, the upper end of said shaft being screw threaded for a short distance and having screw threaded engagement with the upper end of the tube, a head 011 the shaft whereby it may be turned, and a plurality of screw blades attached to the shaft and surrounding the same and contacting at their edges with the inner face of the tube.

4. A non-refillable bottle having a neck, a valve seat supported at the lower end of the neck, a valve hinged to the seat to open outwardly, and a baflle arranged in the bottle neck, said battle consisting of a double screw blade entirely filling the cross section of the neck.

5. A non-refillable bottle having a neck, a tube inserted in the neck, said tube being open at its upper end and having a valve seat at its lower end, an outwardly opening valve at its lower end, a screw-threaded rod entering the upper end of the tube and adapted to engage at its lower end with the valve to hold it closed or allow it to open, that portion of the screw-threaded rod extending through the tube being formed with double screw blades surrounding the axial center of the rod, said screw blades filling the tube, and means for preventing the lifting of the screw blades beyond a point which might permit the entire opening of the valve.

In testimony whereof I affix my signature in presence of two witnesses.
